What to use for garage floor "paint"

I've used the inexpensive Rustoleum 2 part Epoxy with excellent results. Going on six years on a 20 year old concrete garage floor, complete with pits, cracks and numerous oil and paint stains. I'm quite abusive to the floor - dragging jack stands, rolling floor jacks, dropping tools, dragging wood, spilled laquer thinner and numerous other fluids and it's held up exceptionally well.

I've heard many stories about epoxy floor coatings (expensive and cheap) flaking, peeling, etc. and most failures can be attributed to poor surface prep. As with any paint or coating, a thorough cleaning goes a long way toward durability and satisfactory results. Before using the supplied cleaning agent in these kits, I first scrub and rinse real good with Simple Green. Zep Citrus cleaner or even CLR would work too I suppose. Let it dry, then use the supplied cleaner. Allow to dry thoroughly as well before coating.

Unless you're coating some major square footage, the 2 part epoxy should work fine provided you clean real good.
